Fromilre statement already made it will be n-f jJporonlz rho; t-hr construction and operzr tion. of the loom and of a sido motion foeler mechanism In "unchanged by this nwontion which has to do only with rho consrruotion of the shuttle itself, Consequently this dosorlption is restricred'toizhs shuttle.

In its general construction the shuttle may loo of any usno-l type. In the nroforrod form illustrated rho body of the shuttle is provided Witlrtlio usual recess 1 extending through the shnlztlo from top to bottornto .recivo the filling carrier, which, as indicatd in dotted linos may be 21 Wooden bobbin 2 of usual typo. 9111011 :1 filling corner is commonly clamped and held in tho slmt tale recess 1 by a bifnrooted motol (humping guldo shown, togotliorwlth the novel serthe end of rated surface, separately in Fig. 3. The shank 3 of this clamping guide is rigidly secured in the body of the shuttle with the arms 4 and 5 projecting into the recess 1 substantially parallel to the side walls 6 and 7 thereof.,The inner surfaces of these arms are usually grooved at 8 to cooperate with rings 9 on the butt of the filling carrier in accurately positioning and firmly holding the filling carrier.

The side wall 7 is slotted long tudinally at 10 opposite the axis of the filling carrier to enable the feeler to enter the recess 1 and feel. the filling on the filling carrier.

-In the ease of a side motion feeler mechanism, with which the shuttle of this inven-' initiatefilling replenishment or other changes in the operation of the loom.

But, as already pointed out, longitudinal 'mis-positioning of the-shuttle at the time of feeling, due to rebound or improper boxing of the shuttle or other cause, will so relate the shuttle to the path of feeler movement that the feeler will not be opposite the filling on the filling carrier but will be in a position opposite a point nearer the butt of the filling carrier or the butt end of the shuttle recess. Under such conditions, when ;the beat up occurs, the feeler contacts with ;a smooth hard surface which has no relaftion to the condition of the filling on the filling carrier and consequently side motion may take place resulting in premature initiating action of the feeler mechanism.

This result is obviated in the preferred form of the invention illustrated by extending the slot 10 -in the shuttle wall toward the butt end offthe recess 1 suificiently to expose the arm 5 of the bifurcated clamping guide and by serrating as at 11 the external exposed face of this arm 5. It is found in practice that such an extension of the slot 10 for the length of the usual arm 5 is sufiicient to cover the range of shuttle 'mis-positioning for which it is necessary to provide the surface of the arm 5 is shown as serrated by vertical ridges but any form of roughness sufiicient to prevent slde momosses tion of a feeler in contact therewith is to be included as a serrated surface.

Thus. it will be seen that if the shuttle be longitudinally mis-positioned when feeling takes place this invention provides means which prevents premature side motion of the feeler with its consequent premature initiation of filling replenishment or other change in the operation of the loom.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A shuttle for use in side motion feelcr looms provided with a filling carrier rccess and with means to clamp and hold a filling carrier by its butt in said recess, one wall of said recess being slotted to permit the passage of the feeler thercthrough, the said shuttle bein further provided with an external serratef surface located in alinement longitudinally of the shuttle with, but nearer the butt end of the shuttle recess than, the normal path of the feeler movement, whereby, if the shuttle be longitudinally mis-posltioned at the time of feeling, premature actuation of the feeler will be prevented by its engagement with said rated surface.

2. A shuttle for use in side motion feeler looms having the construction defined in claim 1 in which the said serrated surface is located upon the means to clamp and hold the filling carrier by its butt.

3. A shuttle for use in side motion feeler looms provided with a filling carrier recess and with a bifurcated metal clamping guide in said recess to clamp and hold a filling carrier by its butt, one wall of said recess being slottedto permit the passage of the feeler therethrough, the said slot being extended toward the butt end of the shuttle recess and opposite said clamping guide, and the said clamping guide having its external face exposed by said extended slot serrated,

whereby, if the shuttle be longitudinally mis-positioned at the time of feeling, premature actuation of the feeler will be prevented by its engagement with said serrated surface.

4:. A shuttle for use in side motion feeler looms comprising a body havin a filling carrier recess and a slot througi the wall of said recess to permit the passage of the feeler, and comprising means carried by the shuttle and acting when the shuttle is longitudinally mis-positioned at the time of feeling to engage the feeler and prevent premature side motion of the feeler.
